August 1, 2017 – Dinkle International announced the availability of its pluggable terminal blocks, a series of products with a push-in-design for connecting wires to the terminal blocks.
A pluggable terminal block is composed of a plug and a mating socket. The socket is usually attached to a printed circuit board through pins. The plug fits into the socket, and the wires connect to the socket via Dinkle’s patented push-in-design.
Screw terminals take time to tighten properly, and there is always the danger of under torqueing and loose connections, or over torqueing and stripped screw threads. By contrast, wires connected using Dinkle’s push-in-design technology assure a secure connection, with about 75% less time required per wire installation.
Connecting a solid wire with push-in-design takes only 3.6 seconds, compared to 13.5 seconds for a screw connection. A flexible wire takes 4.1 seconds to connect, while a screw terminal takes 14.4 seconds. A flexible wired with a ferrule takes 3.7 seconds to connect, compared to 13.2 seconds for a screw terminal.
Pluggable terminal blocks are available in a variety of sizes and ratings. Pitch varies from 2.54-6.35 mm, with wire ranges from 30-16 to 24-12 AWG. Current ratings are 5-8 amps at 150 Vac, 8-16 amps at 300 Vac, and 20 amps at 600 Vac. Connection methods are V-type spring (not patented), or patented S-Cage single, double and rail type. Value-added customization services include label printing, and supplying blocks in assorted color combinations.
An LED at each connection point is on when current is flowing through the wire, with LED light pipes integral to the terminal block assemblies used to ensure each LED is clearly visible. This indication provides visual confirmation of active connections and is useful for troubleshooting.
Mini type pluggable terminal blocks include the 0225, 0226 and 0227 series. The 0225 series has an ultra-thin housing with a 7mm height, able to accommodate a broad cross section of 1.5 mm² wire. Various selections of mounting methods contribute to a vibration-proof, secure connection. These terminal blocks are suited to installation within PLCs, I/O modules, signal panels, etc.
